Title: Primer device for uncased propellant powder body - which is fired by deformation resistant primer body
Inventor: POLITZER ANTON DIPL ING
IPC: F42C19/085
Filed: 1973-08-03
Abstract: In a primer device placed in a bore of a uncased propellant powder body for a tubular weapon, and consisting of a primer body and primer seat, the primer material is present in the form of a tablet fixed to the base of the bore in the powder body, and is fired by a deformation resistant primer body constructed as a piston-shaped transfer rod displaceably supported in the bore, and more especially made of light material e. g. aluminium alloy or polycarbonate. The primer device reduces the erosion of the striker bolt tip arising in the use of uncased propellant charges for light tubular weapons of calibre up to 30mm. The propellant powder body is composed of two parts, a main body and a cap-shaped insert, fixed together by adhesive, suitably an ethyl acetate solution of cellulose nitrate, and provided with an internal bore. The main body has a stepped bore, the tapering bore accepting the insert, while a primer tablet in the lowest bore projects into bore. A powder ring disc rests on the shoulder and supports the transfer or primer rod, the striker tip of which is separated from the primer tablet by a small gap. Alternatively the primer rod may consist of the nesting units. The end of the bore is covered by a thin layer of the powder body, and is broken through by the striker bolt. When this meets the primer rod it drives this through the powder disc and causes the tip to strike the primer tablet which ignites the powder body and disc by the primer flame as this spreads out on all sides. The powder body and disc may consist of 15% flake powder, size 0.2-0.6mm; 77% graphited spherical powder size 0.4-0.6mm with 15% butyl acetate binder. The primer tablet consists of 42% lead azide; 3% tetrazene; 40% BaNO3; 5% PbO; 10% CaSi2.

Filed: 1973-09-28
Abstract: The bus system circuit arrangement is for used with computers, memory stores and input/output (I/O) channels so as to permit direct access to the memory through the channels without stopping the computer. This is achieved by the connection between the bus head (E) carrying the input data and at least one of those carrying output data (A and R) being closed when there is direct access to the memory. Pref. signals from the memory (S) arriving in the computer via the bus lead (E-bus) are checked for parity and are not decked when they leave the I/O channel (EA). Where a parity bit is used in the memory store (S) the circuitry in the computer is used for its generation, without a parity circuit in the I/O channel being provided.

Title: Coaxial cable connector with tension relief clamp - has flexible angled plates pressed by collar down on and against cable
Inventor: EGGERT HANS
IPC: H02G3/06
Filed: 1973-09-28
Abstract: The connector with tension relief clamp for coaxial cables consists of a lower insulating part enclosing the contact end of the vertical cable, and an upper insulating part formed by a threaded collar that screws down onto the lower part. The lower part has a cavity at the end facing the collar to accept two flexible, angled plates, situated diametrically opposite one another against each side of the cable. The lower ends of these clamping plates are pressed against the bared cable screening by the downward action of the collar, which forces them down against shoulders on the inside of the lower part. The shoulders change the axial force to a radial one.

The contact loop engagement provides lifting of the handset from the apparatus cradle switch.
Patent DE-2404496-A1 (DE)
Title: Monitoring cct. for first digits of dialling signal - blocks or connects subscriber to different value ccts.
Inventor: RIEDMANN GUENTER
IPC: H04M1/677
Filed: 1974-01-31
Abstract: The number of dialled digits, and the number of the same first digits is determined by separate counters. Comparator monitoring readings of both counters blocks or permits the connection build up at first difference between the two readings. Monitoring of counter readings after a certain number of dialled digits is done by a coincidence gate whose inputs are connected to counter outputs corresponding to this number of digits. Its output controls a bistable switching means which in one position allows, and in the other position blocks, the connection build-up. The component units are made as uniform as possible to permit an extensive integration.

Title: Combination coupling with flexible and friction element - has adjustable friction load on taper sleeve for varying torque transmission
Inventor: BETZING RUDOLF
IPC: F16D47/02
Filed: 1974-03-23
Abstract: The coupling has a flexible and a friction coupling. An integral part of the output shaft of the flexible coupling is an integrally tapered sleeve. It houses the tapered friction element which is attached to the output shaft of the friction coupling. The taper is pressed into the friction sleeve by an internal screw ring which applies its axial load through spring washers and a thrust bearing. The setting of the screw ring thus determines at which torque value the friction coupling starts to slip. The spring dished washers act through a thrust ball race which allows relative movement should the coupling slip.
